The Development of a Virtual Laboratory on Electric Vehicle Batteries Using The ADDIE Model

The development of a virtual laboratory on electric vehicle batteries aims tostudy the quality of the virtual laboratory on electric vehicle batteries, compare the learning achievement before and after learning, and examine the satisfaction level of students regarding learning with the virtual laboratory.A sample group consists of 40 first-year students in the Automotive Electrical Technology program at Chonburi Technical College, were selected by simple cluster sampling method. The virtual laboratory is developed using the ADDIE model and includes activities such as using electrical measurement instruments, grouping battery cells, connecting batteries, and connecting Battery Management Systems (BMS) with battery packs. The virtual laboratory, along with the theoretical content, is presented in an online format, allowing students to self-study and conduct experiments on a simulated battery system. Students beable to practice measuring electrical voltage and internal resistance, as well as connecting batteries. The virtual laboratory can also calculate energy (Wh) and capacity (Ah) values.The results of assessing the quality of the virtual laboratory, conducted by 5 content experts, reveal is an exceptionally high (x=4.52, S.D. = 0.48). Additionally, 5 educational technology experts found that the media quality is a very high level (x= 4.48, S.D. = 0.34). The results of comparing the learning achievement of students indicate that the average score before learning was x = 8.20, and the average score after learning was x= 16.05. The post-learning average score is significantly higher than the pre-learning score at a statistical significance level of .05. The study of student satisfaction reveals that it is at the highest level of satisfaction (x= 4.65, S.D. = 0.52). In summary, the virtual laboratory on electric vehicle batteries demonstrates a highly commendable quality in terms of media. The learning achievement of students who studied with the virtual laboratory significantly increased. Moreover, students using the virtual laboratory expressed the highest level of satisfaction.
